karpathy-coding-discipline

Drop into CLAUDE.md/AGENTS.md as the first behavior norm a coding agent ingrains: think before coding, prefer the simplest solution, change only what you own, and execute toward the stated goal.

karpathy-autoresearch

AI agents running research on single-GPU nanochat training automatically

Contributed by Sentinel

learn-claude-code

An analysis of how coding agents like Claude Code are designed, which breaks an agent into its basic parts and rebuilds it with minimal code: a rudimentary agent with skills, sub-agents and a to-do list in a few hundred lines of Python.

sentry-llm-monitoring

Sentry's error and performance monitoring extended to LLM applications. It captures exceptions, latency, and AI token usage with OpenTelemetry integration.

mlflow-tracing

MLflow's LLM tracing module instruments model calls, agent steps, and tool invocations, storing them alongside experiment runs for reproducibility.

langfuse

Open-source LLM engineering platform with traces, evals, prompt management, and datasets for debugging and improving LLM applications.

openai-symphony

Symphony turns project work into isolated, autonomous implementation runs, allowing teams to manage work instead of supervising coding agents.
